[TowerTalk] VHF propagation board/reflector?

[Bill VanAlstyne]

I'm wondering if anyone knows of a VHF propagation discussion board or mail
reflector that is reasonably active and well-known. I've come across a
couple small boards on various websites, but they are mostly moribund and of
little practical use. I'm interested in sharing my experiences, and getting
others' viewpoints and experiences, with sporadic-E and scatter modes on the
50/144 MHz bands. Looking for a reasonably technical bunch that will
challenge me to study, research, and learn.

Also, any really good books, papers, or websites on this subject would be of
extreme interest to me. The ARRL Antenna Book, over 800 pages long,
addresses exactly seven paragraphs specifically to sporadic-E propagation -- 
six, if you don't count the paragraph they waste complaining about people
who refer to sporadic-E as "E-s" or "Ease" instead of as "E-sub-s". <sigh>
